Abstract

The invention relates to a plasma generating device which can generate oxidant containing hydroxyl radicals and carry out oxidation treatment on gas liquid. The plasma generating device comprises a first electrode and a second electrode, wherein at least the first electrode is a metal sheet or a metal bar, the first electrode and the second electrode are connected by an insulation layer and isolated, and the wall thickness of the insulation layer is not more than 0.5mm; the first electrode is accessed into an alternating-current voltage, the second electrode is grounded, the alternating-current voltage applied between the first electrode and the second electrode is not less than 1KV, and the frequency is not less than 500Hz; and the plasma generating device works under the milliampere-class current consumption state. The plasma generating device can decompose and treat organic matters, treat toxic and harmful gases, eliminate peculiar smells of gases, decompose the organic matters in the air and treat to reach the emission standards, and has the advantages of low operation cost, relatively small device, low energy consumption and remarkable energy saving and environmental protection without adding any chemical medicines or other auxiliary treatment means during the use.

Description

technical field [0001] The invention relates to a plasma generation device related to the generation of plasma in liquid and gas, especially a plasma generating device suitable for water treatment, waste water treatment or poisonous and harmful gas treatment. Background technique [0002] The main working principle of the plasma generator is to apply an AC high voltage above 0.5KHZ between the first electrode and the second electrode, and use positive and negative high voltage ionized air to generate plasma through electrode capacitance discharge. At the same time, when the positive and negative ions neutralize the positive and negative charges in the air, a huge energy release is generated, which leads to the change of the molecular structure of the surrounding gas substances, and realizes the sterilization, disinfection and deodorization of gases and liquids. [0003] There are roughly three types of plasma generation methods associated with liquids. The first type is to ...
